Montana
Montana lies along the northern Rocky Mountains where alpine environments transition eastward into the grasslands of the Great Plains. This meeting of mountain and prairie landscapes has long shaped travel routes, trade networks, and cultural exchange across the northern interior of North America. Major river systems, including the Missouri and Yellowstone Rivers, provided corridors of exploration and settlement, linking the region to broader continental patterns of movement extending from the Rocky Mountains to the Mississippi Valley.
The alpine landscapes preserved in Glacier National Park and the internationally connected Waterton-Glacier International Peace Park illustrate one of North America’s most intact mountain ecosystems, shaped by glacial forces that carved valleys, lakes, and high elevation habitats across the Continental Divide. The historic travel corridors of the Missouri River are preserved within Upper Missouri River Breaks National Monument, where dramatic cliffs and prairie landscapes remain similar to those encountered by the Lewis and Clark Expedition. Nearby, Pompeys Pillar National Monument contains the only remaining physical evidence of William Clark’s 1806 signature along the expedition route.
Additional sites illustrate the complex cultural history of the northern Plains and Rocky Mountain frontier. Fort Union Trading Post National Historic Site reflects the economic networks of the nineteenth-century fur trade, while Little Bighorn Battlefield National Monument preserves a landscape associated with conflict and changing relationships between Indigenous nations and the United States during westward expansion. Together, these landscapes position Montana as a geographic crossroads where mountain ecosystems, river corridors, and historical encounters shaped the development of the American West.
